Enphase Energy shares plummet as Q3 outlook falls short and tariffs weigh on performance.

Enphase Energy shares fell in premarket trading after the company issued lower revenue guidance for Q3 and flagged the impact of newly imposed tariffs. The solar inverter maker expects revenue to be within a range of $480-500 million, below the consensus estimate of $520 million. The company also cited ongoing supply chain challenges and concerns about the impact of tariffs on its business.

Enphase Energy, Inc. (NASDAQ: ENPH), a leading provider of solar energy technology, saw its shares drop in premarket trading on July 2, 2025, after the company issued lower revenue guidance for the third quarter. The global energy technology company expects revenue to be within a range of $330 million to $370 million, falling short of the consensus estimate of $368.4 million. This weaker-than-expected outlook, coupled with ongoing supply chain challenges and concerns about the impact of tariffs, has driven the negative market reaction.

Enphase Energy reported adjusted earnings per share of $0.69 for the second quarter, exceeding the analyst consensus of $0.64. Revenue came in at $363.2 million, slightly above the consensus estimate of $361.9 million and up 19.7% compared to the same quarter last year. However, the company's third-quarter revenue guidance has been a source of concern for investors [1].

"We reported quarterly revenue of $363.2 million in the second quarter of 2025, along with 48.6% for non-GAAP gross margin," said Badri Kothandaraman, President and CEO of Enphase Energy. "We shipped approximately 1.53 million microinverters, or 675.4 megawatts DC, and 190.9 megawatt hours (MWh) of IQ Batteries" [1].

The company's U.S. revenue increased approximately 3% compared to the first quarter, which Enphase attributed to seasonality partially offset by lower safe harbor revenue. European revenue grew approximately 11%, primarily due to higher microinverter and battery sales [1].

Enphase continued to expand its domestic manufacturing capabilities, shipping approximately 1.41 million microinverters and a record 46.9 MWh of IQ Batteries from U.S. facilities during the quarter. The company also noted that its IQ Meter Collar has now been approved by 29 U.S. utilities [1].

The company ended the quarter with $1.53 billion in cash, cash equivalents, and marketable securities, and generated $18.4 million in free cash flow [1].

Enphase Energy's strategic vulnerabilities are not insurmountable but require careful navigation. The green energy sector is undergoing a seismic shift, with policy uncertainty, shifting demand dynamics, and margin pressures creating a volatile environment. The company's reliance on a narrow product portfolio (microinverters and batteries) makes it more susceptible to sector-specific shocks compared to diversified players like SunPower or Vivint Solar [3].

Investors should monitor Trump administration actions on tariffs and tax credits, as a reversal or extension of IRA incentives could significantly alter Enphase's trajectory. Additionally, watching Q3 2025 results for signs of cost management and supply chain optimization, and comparing Enphase's R&D spend and product diversification to rivals like SolarEdge and Tesla, are key considerations [3].
